The renewable energy covered 42.2 percent of the electricity demand in mainland Spain in 2013 with wind energy being the main contributor, a study published by the Spanish Electricity Network (Red Electica Espanola) revealed.
Wind energy produced 21.2 percent of the country’s electricity, 3.1 percent up on the 18.1 percent from 2012.
Meanwhile, the hydro-electric power contributed 14.6 percent of needs, while solar power covered 4.8 percent of demand, renewable thermal energy two percent and other sources accounted for the remainder.
In case of the advanced renewable energy sources, there was a one percent reduction in electricity produced from nuclear power plants, while there was a drop in the use of carbon based fuels, stated the report.
The percentage of electricity produced by carbon based fuels dropped to 14.6 percent in 2013 from 19.3 percent in the previous year.
This led to a considerable carbon emission reduction, with 60 million tons less of carbon entering the atmosphere than in 2012.
